FIELD OF THE INVENTION

[0001] This invention relates to a new emulsifier compound withparticular contents of fatty alcohols, ethoxylated fatty alcohols andselected oil and wax components and to the use of the emulsifiercompounds for the production of cosmetic and/or pharmaceuticalpreparations.

PRIOR ART

[0002] Consumers expect cosmetic skin- and hair-care emulsions tosatisfy a range of requirements. Apart from the cleaning andskin-/hair-care effects which determine the intended application, valueis placed on such diverse parameters as very high dermatologicalcompatibility, elegant appearance, optimal sensory impression andstability in storage. Some of these features, such as dermatologicalcompatibility for example, can largely be objectively determined by thecosmetic chemist. However, when it comes to sensory impression,evaluation by volunteers is, ultimately, always subjective.

[0003] From the emulsion technology perspective, it is particularlyimportant to provide emulsifiers and emulsifier combinations whichproduce fine-droplet and storable emulsions. Accordingly, there isalways interest in the development of new emulsifier combinations whichenable particularly stable, fine-droplet emulsions to be formulated.Reference may be made in this connection to the articles by A. Ansmann[Seifen-Öle-Fette-Wachse, 117, 518 (1991)], C. Cabeta [SÖFW-Journal,120, 162 (1994)], P. Hameyer [SÖFW-Journal, 121, 216 (1995)] and, inparticular, A. Wadle [Parf. Kosm. 77, 250 (1996)].

[0004] Although the expert knows of measures by which, in principle,fine-droplet and storable emulsions can be obtained, known emulsions arestill not entirely satisfactory due to the choice of emulsifiers used.Emulsions are normally stabilized by a combination of emulsifiers. Theself-emulsifiable mixtures based on fatty alcohols known, for example,from EP 0 553 241 (SEPPIC) or WO 97/18033 (fatty alcohol/alkylpolyglycoside mixtures) are often used for this purpose. The emulsifiermixtures obtainable under the names of Cetomacrogol® Emulsifying Wax(British Pharmacopeia), Cire de Lanol® CTO (Seppic S.A.), Sinnowax® AO(Cognis France, S.A.), Promulgen® D (Amerchol) are mentioned solely asexamples of the fatty alcohol/fatty alcohol ethoxylate combination.Emulsifier mixtures based on fatty alcohol/alkyl polyglucoside/partialglyceride are known from International patent application WO 92/07543.

[0005] The emulsifier mixtures commercially available at the presenttime are often unsuitable for the production of low-viscosity o/wemulsions for which there is presently an increasing demand on thecosmetics market. Besides poor emulsion stability, changes in viscosityoften occur during storage, particularly at elevated temperatures. Atthe same time, viscosity is often dependent on the shear rate in theindustrial production process, so that products with differentviscosities are obtained from different production plants. Suchvariations are not acceptable in the manufacture of cosmetic products orto the consumer.

[0006] Accordingly, the problem addressed by the present invention wasto provide emulsifier mixtures (compounds) for the production ofcosmetic products, more particularly thinly liquid low-viscosity o/wemulsions, with which it would be possible to obtain stable emulsionswhose viscosity would not be affected by the shear rate duringproduction and would not change even during storage under temperaturestress (−5 to 50° C.). In addition, the emulsifier mixtures would havegood skin-care effects and improved sensory properties that would allowthe production of sensorially “lights” products. Another problemaddressed by the invention was to provide emulsifier mixtures that wouldenable the formation of microfoam on the skin—known among experts as“white residue”—to be reduced. A further problem addressed by theinvention was to provide emulsifier mixtures that would enable stableemulsions with a high salt content to be produced.

DESCRIPTION OF THE INVENTION

[0007] It has been found that emulsifier mixtures with a particularcontent of fatty alcohols, fatty alcohol ethoxylates and special oil orwax components not only have excellent sensory and care properties, theyalso afford advantages from the emulsion technology perspective.

[0008] The present invention relates to emulsifier mixtures containing

[0009] (a) 0.1 to 60% by weight of a fatty alcohol or fatty alcoholmixture,

[0010] (b) 30 to 97% by weight of an ethoxylated fatty alcohol ormixture of ethoxylated fatty alcohols,

[0011] (c) 0.1 to 20% by weight of a dialk(en)yl ether, a dialk(en)ylcarbonate or a mixture of these components,

[0012] (d) less than 10% by weight of water.

[0013] Components (a), (b) and (c) of the emulsifier compositionsaccording to the invention may also add up to 100%, i.e. the emulsifiercomposition could consist largely of these components except forsecondary products originating from the raw materials used and residualwater, although such secondary products and residual water may bepresent. However, the emulsifier mixture according to the invention mayalso contain other components. The quantity of water in the emulsifiermixture is less than 10% by weight and preferably less than 5% byweight.

[0014] Highly stable emulsions, more particularly thinly liquidlow-viscosity o/w emulsions, can be produced with the emulsifiermixtures according to the invention. The resulting emulsions areparticularly stable in storage and do not undergo any significantchanges in viscosity, even under temperature stress (storage conditions:84 days at −5 to 50° C.). The “compounds” according to the inventionallow the formulation of emulsions whose viscosity is not dependent onthe shear rate during the production process. In addition, thecombination according to the invention contributes towards a reductionin microfoam formation which often occurs in emulsions containing waxcomponents. In particular, very light and stable emulsions withrelatively high salt concentrations, more especially thinly liquidantiperspirant roll-on formulations containing aluminum chlorohydratesand similar salts, can be produced using the emulsifier mixtureaccording to the invention.

[0015] A preferred embodiment of the emulsifier mixture contains acombination of (a) 2 to 60% by weight of a fatty alcohol or fattyalcohol mixture, (b) 30 to 90% by weight of an ethoxylated fatty alcoholor mixture of ethoxylated fatty alcohols and (c) 0.2 to 15% by weight ofa dialk(en)yl ether, a dialk(en)yl carbonate or a mixture of thesecomponents. A particularly preferred embodiment contains a combinationof (a) 10 to 55% by weight of a fatty alcohol or fatty alcohol mixture,(b) 30 to 85% by weight of an ethoxylated fatty alcohol or mixture ofethoxylated fatty alcohols and (c) 0.5 to 15% by weight of andialk(en)yl ether, a dialk(en)yl carbonate or a mixture of thesecomponents.

[0016] The present invention also relates to the use of the emulsionconcentrates according to the invention for the production of cosmeticand pharmaceutical preparations. The emulsion mixtures are preferablyused for the production of o/w emulsions. In a particularly preferredembodiment, they are used for stabilizing thinly liquid o/w emulsionswith viscosities of 100 to 20,000 mPa.s (Brookfield RVF, spindle 5, 10r.p.m., 23° C.), more particularly for the production of antiperspirantroll-on formulations.

[0017] Fatty Alcohols (Emulsifier Component a)

[0018] Fatty alcohols in the context of the invention are primaryaliphatic, branched or unbranched, saturated or unsaturated, optionallyhydroxy-substituted alcohols with a C₆₋₅₄ hydrocarbon radical.

[0019] Typical examples are caproic alcohol, caprylic alcohol,2-ethylhexyl alcohol, capric alcohol, lauryl alcohol, isotridecylalcohol, myristyl alcohol, cetyl alcohol, isocetyl alcohol, palmitoleylalcohol, stearyl alcohol, isostearyl alcohol, oleyl alcohol, elaidylalcohol, petroselinyl alcohol, linolyl alcohol, linolenyl alcohol,elaeostearyl alcohol, ricinolyl alcohol, hydroxystearyl alcohol,dihydroxystearyl alcohol, arachyl alcohol, gadoleyl alcohol, behenylalcohol, erucyl alcohol and brassidyl alcohol and the technical mixturesthereof obtained, for example, in the high-pressure hydrogenation oftechnical methyl esters based on fats and oils or aldehydes fromRoelen's oxo synthesis and as monomer fraction in the dimerization ofunsaturated fatty alcohols. Other examples are the Guerbet alcoholsbased on C₆₋₁₈ fatty alcohols and technical dimer diols and trimertriols containing 18 to 36 or 18 to 54 carbon atoms which emanate fromthe oligomerization and subsequent hydrogenation of unsaturated fattyacids.

[0020] Emulsifier mixtures of which the fatty alcohol component (a) isselected from the group of C₁₂₋₂₄ fatty alcohols are preferred for thepurposes of the invention. A particularly preferred embodiment ischaracterized by the use of technical C₁₆₋₁₈ fatty alcohols such as, forexample, cetylstearyl alcohol, isostearyl alcohol and Guerbet alcoholsof corresponding chain length. It is particularly preferred to use C₁₆,C₁₈ and C_(16/18) fatty alcohols in a quantity of 0.1 to 60% by weightand more particularly 10 to 55% by weight, based on the overallcomposition of the emulsifier mixture.

[0021] Fatty Alcohol Ethoxylates (Component b)

[0022] Fatty alcohol ethoxylates suitable for use as component (b) areproducts of the addition of ethylene oxide onto primary alcohols. Theethoxylates are produced by known methods and are basically mixtures.Depending on their production, they may have a conventional broadhomolog distribution or a narrow homolog distribution. The degree ofethoxylation (EO: number of ethylene oxide units added on) represents aGauss distribution, the maximum of the Gauss curve being referred tohere as the average degree of ethoxylation n.

[0023] According to the invention, a combination of addition productswith a low (n=1 to 5 EO) and relatively high average degree ofethoxylation (n=6-35 EO) is preferred. The EO figures are always basedon the maximum of the Gauss distribution, i.e. the average degree ofethoxylation. Component (b) of the emulsifier mixture according to theinvention preferably contains a combination of (b1) a C₁₂₋₂₄ fattyalcohol+1 to 5 EO and (b2) a C₁₂₋₂₄ fatty alcohol+6 to 35 EO. Aparticularly preferred embodiment of the invention is characterized bythe use of a three-component combination in which component (b) containsa mixture of (b1) C₁₂₋₂₄ fatty alcohols+1 to 5 EO, (b2) C₁₂₋₂₄ fattyalcohols+6 to 16 EO and (b3) C₁₂₋₂₄ fatty alcohols+18 to 35 EO. Acombination of (b1) C₁₈ fatty alcohol+1 to 2 EO, (b2) C_(16/18) fattyalcohol+10 to 12 EO and (b3) C_(16/18) fatty alcohol+18 to 22 EO is mostparticularly preferred. The three-component combination is advantageousfrom the emulsion technology perspective, so that particularly stableemulsions are formed, and also leads to products with better sensoryproperties. A particularly preferred combination of component (b) is amixture of Eumulgin® S, Eumulgin® B1 and Eumulgin® B2 which are marketedby Cognis Deutschland GmbH. Eumulgin® S is a mixture of stearyl alcoholand Steareth-2.

[0024] The production of these nonionic surfactants corresponds to theforegoing description. Typical examples are products of the addition ofethylene oxide onto caproic alcohol, caprylic alcohol, 2-ethylhexylalcohol, capric alcohol, lauryl alcohol, isotridecyl alcohol, myristylalcohol, cetyl alcohol, palmitoleyl alcohol, stearyl alcohol, isostearylalcohol, oleyl alcohol, elaidyl alcohol, petroselinyl alcohol, linolylalcohol, linolenyl alcohol, elaeostearyl alcohol, arachyl alcohol,gadoleyl alcohol, behenyl alcohol, erucyl alcohol and brassidyl alcoholand technical mixtures thereof. The addition products of ethylene oxideonto cetearyl alcohol, stearyl alcohol, isostearyl alcohol or behenylalcohol are particularly preferred.

[0025] Dialk(en)yl Ethers and Dialk(en)yl Carbonates (component C)

[0026] The purposeful choice of component (c)—even when added in arelatively small quantity—gives the emulsifier mixture better sensoryproperties. The resulting emulsions formulated with the mixtureaccording to the invention are more stable and impart a lighter and lessgreasy feeling on the skin. Component (c) is present in a quantity of0.1 to 20% by weight, preferably 0.2 to 15% by weight, 0.5 to 15 andmore particularly 0.5 to 5% by weight, based on the overall compositionof the emulsifier mixture.

[0027] The dialk(en)yl ethers may be symmetrical or nonsymmetrical,branched or unbranched, saturated or unsaturated. C₆₋₃₂ dialkyletherssuch as, for example, di-n-octyl ether, di-(2-ethylhexyl)-ether, laurylmethyl ether or octyl butyl ether and didodecyl ether are particularlysuitable for the purposes of the invention. C₁₆₋₃₂ dialkylethers aremost particularly preferred because they also act as consistencyfactors. C₁₆₋₂₄ dialkylethers are particularly preferred, distearylether and dibehenyl ether being the most suitable.

[0028] The compounds may be prepared from fatty alcohols in the presenceof acidic catalysts by generally known methods, cf. for example DE 19511 668 A1 and DE 198 31 705 A1 and DE 199 43 585. Typical examples ofsuch ethers are products obtained by etherification of caproic alcohol,caprylic alcohol, 2-ethylhexyl alcohol, capric alcohol, lauryl alcohol,myristyl alcohol, cetyl alcohol, palmitoleyl alcohol, stearyl alcohol,isostearyl alcohol, elaidyl alcohol, petroselinyl alcohol, linolylalcohol, linolenyl alcohol, oleyl alcohol, ricinolyl alcohol,elaeostearyl alcohol, arachidyl alcohol, gadoleyl alcohol, behenylalcohol, erucyl alcohol and brassidyl alcohol, Guerbet alcohols and thetechnical mixtures thereof obtained, for example, in the high-pressurehydrogenation of technical methyl esters based on fats and oils.

[0029] The dialk(en)yl carbonates may be symmetrical or nonsymmetrical,branched or unbranched, saturated or unsaturated. Among the dialk(en)ylcarbonates, linear or branched, saturated or unsaturated C₆₋₃₂dialkyl(ene) carbonates, such as dihexyl, dioctyl, di-(2-ethylhexyl) ordioleyl carbonate for example, are preferred for the purposes of theinvention. Wax-like C₁₆₋₃₂ dialkyl(ene) carbonates are particularlypreferred because they also act as consistency factors. C₁₆₋₂₄dialkyl(ene) carbonates are particularly preferred and, of these,saturated unbranched C₁₆₋₂₂ dialkyl carbonates are preferred, distearylcarbonate being particularly suitable.

[0030] The compounds may be prepared by transesterification of dimethylor diethyl carbonate with the corresponding hydroxy compounds by knownmethods; a relevant overview can be found in Chem. Rev. 96, 951 (1996).Typical examples of dialkyl(ene) carbonates are transesterificationproducts of dimethyl and/or diethyl carbonate with caproic alcohol,caprylic alcohol, 2-ethylhexyl alcohol, capric alcohol, lauryl alcohol,myristyl alcohol, cetyl alcohol, palmitoleyl alcohol, stearyl alcohol,isostearyl alcohol, elaidyl alcohol, petroselinyl alcohol, linolylalcohol, linolenyl alcohol, oleyl alcohol, ricinolyl alcohol,elaeostearyl alcohol, arachidyl alcohol, gadoleyl alcohol, behenylalcohol, erucyl alcohol and brassidyl alcohol, Guerbet alcohols and thetechnical mixtures thereof obtained, for example, in the high-pressurehydrogenation of technical methylesters based on fats and oils.

[0031] A preferred embodiment of the emulsifier mixture contains thefollowing components:

[0032] (a) 0.1-60% by weight of a C₁₂₋₂₄ fatty alcohol,

[0033] (b1) 10-65% by weight of a C₁₂₋₂₄ fatty alcohol+1-5 EO,

[0034] (b2) 10-30% by weight of a C₁₂₋₂₄ fatty alcohol+6-16 EO,

[0035] (b3) 10-20% by weight of a C₁₂₋₂₄ fatty alcohol+18-35 EO and

[0036] (c) 0.1 to 15% by weight of a C₆₋₃₂ dialk(en)yl ether, a C₆₋₃₂dialk(en)yl carbonate or a mixture of these components.

[0037] Partial Glycerides

[0038] In another preferred embodiment, the emulsifier mixture accordingto the invention additionally contains a partial glyceride. Partialglycerides support the development of lamellar phases in the aqueousphase of the emulsions which leads to a further improvement in theskin-care effect on application to the skin. The partial glyceride maybe present in a quantity of 0.1 to 10% by weight, preferably 0.1 to 5%by weight and more particularly 0.1 to 3% by weight, based on theoverall composition of the emulsifier mixture.

[0039] Fatty acid partial glycerides are known substances which may beprepared by the relevant methods of preparative organic chemistry. Theyare normally mixtures of mono- and diglycerides which are obtained bytransesterification of the corresponding triglycerides with glycerol orby selective esterification of fatty acids. The mixtures may stillcontain small quantities of triglycerides from the production process.The removal of unreacted starting materials and the enrichment ofmonoglycerides in the mixtures are normally achieved by moleculardistillation. Typical examples are technical mono- and/or diglyceridesderived from the following fatty acids: caproic acid, caprylic acid,2-ethylhexanoic acid, capric acid, lauric acid, isotridecanoic acid,myristic acid, palmitic acid, palmitoleic acid, stearic acid, isostearicacid, oleic acid, elaidic acid, petroselic acid, linoleic acid,linolenic acid, elaeostearic acid, arachic acid, gadoleic acid, behenicacid and erucic acid and the technical mixtures thereof obtained, forexample, in the pressure hydrolysis of natural fats and oils and in theoxidation of aldehydes from Roelen's oxosynthesis. The use of partialglycerides based on stearic acid or tallow fatty acid is particularlypreferred.

[0040] Among the fatty acids, unbranched, saturated C₈₋₂₄ fatty acids,especially C₁₂₋₁₈ fatty acids, are preferred for the purposes of theinvention. In a preferred embodiment, the emulsifier mixture contains aC₁₂₋₁₈ partial glyceride. A particularly preferred embodiment of theinvention is characterized by the use of partial glycerides selectedfrom the group of glycerol monoesters or by the use of technicalmixtures with a glycerol monoester content of 30 to 90% by weight. Suchmixtures show the most optimal development of lamellar phases and hencethe most optimal skin-care effect.

[0041] Another preferred embodiment of the emulsifier mixture contains

[0042] (a) 0.1-60% by weight of a C₁₂₋₂₄ fatty alcohol,

[0043] (b1) 10-65% by weight of a C₁₂₋₂₄ fatty alcohol+1-5 EO,

[0044] (b2) 10-30% by weight of a C₁₂₋₂₄ fatty alcohol+6-16 EO,

[0045] (b3) 10-20% by weight of a C₁₂₋₂₄ fatty alcohol+18-35 EO,

[0046] (c) 0.1 to 15% by weight of a C₆₋₃₂ dialk(en)yl ether, a C₆₋₃₂dialk(en)yl carbonate or a mixture of these components,

[0047] (d) 0.1 to 10% by weight of a C₁₂₋₂₈ partial glyceride.

[0048] Cosmetic and Pharmaceutical Preparations

[0049] The emulsifier compound according to the invention isadvantageously used for the production of cosmetic and pharmaceuticalbody-care and cleaning preparations such as, for example, lotions,sprayable emulsions, sun protection compositions, shampoos, showerbaths, antiperspirants, etc. Accordingly, the present invention alsorelates to cosmetic preparations containing 2 to 20% by weight of theemulsifier concentrates. These cosmetic preparations are o/w emulsionswith a water content of preferably more than 50% by weight, based on thepreparation. These preparations normally contain a number of othercomponents typically encountered in cosmetic products, such as fats,oils, ester oils, waxes, humectants and hydrotropes, other emulsifiersand co-emulsifiers, surfactants, solubilizers, inflammation inhibitors,active principles, thickeners, plant extracts, etc. and water. Someclasses of the compounds in question are mentioned purely by way ofexample in the following.

The quantity of oil components in the cosmeticpreparations is normally between 1 and 20% by weight and preferablybetween 1 and 15% by weight, based on the overall composition of thepreparation.

[0052] Surfactants

[0053] The emulsions obtainable with the aid of the emulsifiersaccording to the invention may contain additional anionic, nonionic,cationic and/or amphoteric or zwitterionic surfactants and emulsifiersas further components according to the particular application envisaged.

[0054] Typical examples of anionic surfactants, which are used above allin shower baths and shampoo formulations, are alkyl benzenesulfonates,alkanesulfonates, olefin sulfonates, alkylether sulfonates, glycerolether sulfonates, α-methyl ester sulfonates, sulfofatty acids, alkylsulfates, fatty alcohol ether sulfates, glycerol ether sulfates, hydroxymixed ether sulfates, monoglyceride (ether) sulfates, fatty acid amide(ether) sulfates, mono- and dialkyl sulfosuccinates, mono- and dialkylsulfosuccinamates, sulfotriglycerides, amide soaps, ether carboxylicacids and salts thereof, fatty acid isethionates, fatty acidsarcosinates, fatty acid taurides, acyl lactylates, acyl tartrates, acylglutamates, acyl aspartates, alkyl oligoglucoside sulfates, proteinfatty acid condensates (particularly wheat-based vegetable products) andalkyl (ether) phosphates.

Typical examples of amphoteric orzwitterionic surfactants are alkylbetaines, alkylamidobetaines,aminopropionates, aminoglycinates, imidazolinium betaines andsulfobetaines.

[0057] The surfactants mentioned are all known compounds. Information ontheir structure and production can be found in relevant synoptic works,cf. for example J. Falbe (ed.), “Surfactants in Consumer Products”,Springer Verlag, Berlin, 1987, pages 54 to 124 or J. Falbe (ed.),“Katalysatoren, Tenside und Mineralöladditive (Catalysts, Surfactantsand Mineral Oil Additives)”, Thieme Verlag, Stuttgart, 1978, pages123-217.

[0058] Other Auxiliaries and Additives

[0059] The emulsions may be used as skin-care preparations such as, forexample, day creams, night creams, skin-care creams, nourishing creams,body lotions, ointments and the like and may contain co-emulsifiers,cationic polymers, silicones, superfatting agents, fats, waxes,stabilizers, biogenic agents, glycerol, preservatives, dyes and perfumesas further auxiliaries and additives.

[0060] Suitable cationic polymers are, for example, cationic cellulosederivatives, cationic starch, copolymers of diallyl ammonium salts andacrylamides, quaternized vinyl pyrrolidone/vinyl imidazole polymers suchas, for example, Luviquat® (BASF AG, Ludwigshagen/FRG), condensationproducts of polyglycols and amines, quaternized protein polypeptidessuch as, for example, Lauryldimonium Hydroxypropyl Hydrolyzed Collagen(Lamequat® L, Grünau GmbH), polyethyleneimine, cationic siliconepolymers such as, for example, amodimethicone or Dow Corning (Dow ComingCo., USA), copolymers of adipic acid and dimethylaminohydroxypropyldiethylenetriamine (Cartaretine®, Sandoz/CH), polyaminopolyamides asdescribed, for example, in FR-A 2252840 and crosslinked water-solublepolymers thereof, cationic chitin derivatives such as, for example,quaternized chitosan, optionally in microcrystalline distribution,cationic guar gum such as, for example, Jaguar® CBS, Jaguar®C-17,Jaguar® C-16 of Celanese/USA and quaternized ammonium salt polymers suchas, for example, Mirapol® A-15, Mirapol® AD-1, Mirapol® AZ-1 ofMiranol/USA.

[0061] Suitable silicone compounds are, for example, dimethylpolysiloxanes, methylphenyl polysiloxanes, cyclic silicones and amino-,fatty acid-, alcohol-, polyether-, epoxy-, fluorine- and/oralkyl-modified silicone compounds. Superfatting agents may be selectedfrom such substances as, for example, polyethoxylated lanolinderivatives, lecithin derivatives, polyol fatty acid esters,monoglycerides and fatty acid alkanolamides, the fatty acidalkanolamides also serving as foam stabilizers. Typical examples of fatsare glycerides while suitable waxes are inter alia beeswax, paraffin waxor microwaxes, optionally in combination with hydrophilic waxes, forexample cetyl stearyl alcohol. Metal salts of fatty acids such as, forexample, magnesium, aluminum and/or zinc stearate may be used asstabilizers. In the context of the invention, biogenic agents are, forexample, plant extracts and vitamin complexes. Suitable preservativesare, for example, phenoxyethanol, formaldehyde solution, parabens,pentanediol or sorbic acid. Suitable pearlizing components are, forexample, glycol distearic acid esters, such as ethylene glycoldistearate, and fatty acid monoglycerol esters. The dyes used may beselected from any of the substances which are approved and suitable forcosmetic purposes, as listed for example in the publication “KosmetischeFärbemittel” of the Farbstoffkommission der DeutschenForschungsgemeinschaft, published by Verlag Chemie, Weinheim, 1984,pages 81-106.

[0062] Antiperspirant Formulations

[0063] The emulsifier mixture according to the invention may be usedwith most particular preference for the formulation of deodorant andantiperspirant formulations which have improved sensory properties. Moreparticularly, thinly liquid or so-called roll-on antiperspirantformulations are often unstable because of the high salt concentration,i.e. the emulsion breaks or changes viscosity particularly easily duringstorage. This results in antiperspirant products with very differentviscosities according to the shear rate in the production process.

[0064] By contrast, very stable and constant product properties can beestablished with the emulsifier mixture according to the invention. Theproducts show a distinct reduction in microfoam formation (“whiteresidue”). Accordingly, a preferred embodiment of the cosmeticpreparations are formulations containing antiperspirant components, moreparticularly roll-on formulations with a viscosity of 1,000 to 20,000mPa.s (Brookfield RVT, spindle 5, 10 r.p.m., temperature 23° C.).

[0065] The antiperspirant components are present in the compositionsaccording to the invention in a quantity of 0.1 to 30% by weight,preferably 5 to 25% by weight and more particularly 10 to 25% by weight(based on the quantity of active substance). Suitable antiperspirantcomponents are, for example, aluminum chlorohydrates, aluminum/zirconiumchlorhydrates and zinc salts. These antiperspirants probably act bypartially blocking the sweat glands through the precipitation ofproteins and/or polysaccharides. Besides the chlorohydrates, aluminumhydroxylactates and acidic aluminum/zirconium salts may also be used.For example, an aluminum chlorohydrate which corresponds to the formula[Al₂(OH)₅Cl].2.5H₂O and which is particularly preferred for the purposesof the invention is commercially available under the name of Locron®from Clariant GmbH. The Aluminum Zirconium Tetrachlorohydrex Glycinecomplexes marketed, for example, by Reheis under the name of Rezal® 36Gare also preferably used in accordance with the invention. Othersuitable deodorizing components are esterase inhibitors, preferablytrialkyl citrates, such as trimethyl citrate, tripropyl citrate,triisopropyl citrate, tributyl citrate and, in particular, triethylcitrate (Hydagen® CAT, Cognis Deutschland GmbH). Esterase inhibitorsinhibit enzyme activity and thus reduce odor formation. The free acid isprobably released through the cleavage of the citric acid ester,reducing the pH value of the skin to such an extent that the enzymes areinhibited. Other esterase inhibitors are sterol sulfates or phosphatessuch as, for example, lanosterol, cholesterol, campesterol, stigmasteroland sitosterol sulfate or phosphate, dicarboxylic acids and estersthereof, for example glutaric acid, glutaric acid monoethyl ester,glutaric acid diethyl ester, adipic acid, adipic acid monoethyl ester,adipic acid diethyl ester, malonic acid and malonic acid diethyl ester,hydroxycarboxylic acids and esters thereof, for example citric acid,malic acid, tartaric acid or tartaric acid diethyl ester. Antibacterialagents which influence the germ flora and destroy or inhibit the growthof perspiration-decomposing bacteria, may also be present in theemulsions. Examples of such antibacterial agents are chitosan,phenoxyethanol and chlorhexidine gluconate.5-Chloro-2-(2,4-dichlorophenoxy)-phenol, which is marketed under thename of Irgasan® by Ciba-Geigy of Basel, Switzerland, has also proved tobe particularly effective. However, the emulsifier combination may alsobe used with advantage for the formulation of antiperspirant creams.Accordingly, the present invention also relates to antiperspirant creamswith a viscosity of 20 to 800 Pa.s (Brookfield RVT, spindle 5, 10r.p.m., temperature 23° C. for viscosities of 20 to 40 Pa.s andBrookfield RVT, spindle TE, 4 r.p.m., temperature 23° C. for viscositiesof 40 to 800 Pa.s).

[0066] Sun Protection Formulations

[0067] Sun protection formulations are also particularly easy toformulate with the emulsifier mixture according to the invention. The UVprotection factors are very easy to incorporate; the end formulationsshow long-term stability, even when stored under temperature stress.Accordingly, the present invention also relates to cosmetic preparationscontaining UV protection factors.

[0068] The UV protection factors are present in the compositionsaccording to the invention in a total quantity of 1 to 30% by weight,preferably 5 to 25% by weight and more particularly 5 to 15% by weight(based on the quantity of active substance).

[0069] UV protection factors in the context of the invention are, forexample, organic substances (light filters) which are liquid orcrystalline at room temperature and which are capable of absorbingultraviolet radiation and of releasing the energy absorbed in the formof longer-wave radiation, for example heat. UV-B filters can beoil-soluble or water-soluble. The following are examples of oil-solublesubstances:

[0070] 3-benzylidene camphor or 3-benzylidene norcamphor and derivativesthereof, for example 3-(4-methylbenzylideneycamphor;

[0071] 4-aminobenzoic acid derivatives, preferably4-(dimethylamino)-benzoic acid-2-ethylhexyl ester,4-(dimethylamino)benzoic acid-2-octyl ester and 4-(dimethylaminoybenzoicacid amyl ester;

[0072] esters of cinnamic acid, preferably 4-methoxycinnamicacid-2-ethylhexyl ester, 4-methoxycinnamic acid propyl ester,4-methoxycinnamic acid isoamyl ester, 2-cyano-3,3-phenylcinnamicacid-2-ethylhexyl ester (Octocrylene);

[0073] esters of salicylic acid, preferably salicylic acid-2-ethylhexylester, salicylic acid-4-isopropylbenzyl ester, salicylic acidhomomenthyl ester;

[0074] derivatives of benzophenone, preferably2-hydroxy-4-methoxybenzophenone,2-hydroxy-4-methoxy-4′-methylbenzophenone,2,2′-dihydroxy-4-methoxybenzophenone;

[0075] esters of benzalmalonic acid, preferably 4-methoxybenzalmalonicacid di-2-ethylhexyl ester;

[0076] triazine derivatives such as, for example,2,4,6-trianilino-(p-carbo-2′-ethyl-1′-hexyloxy)1,3,5-triazine and OctylTriazone;

[0077] propane-1,3-diones such as, for example,1-(4-tert.butylphenyl)3-(4′-methoxyphenyl)propane-1,3-dione;

[0078] ketotricyclo(5.2.1.0)decane derivatives.

[0079] Suitable water-soluble substances are

[0080] 2-phenylbenzimidazole-5-sulfonic acid and alkali metal, alkalineearth metal, ammonium, alkylammonium, alkanolammonium and glucammoniumsalts thereof;

[0081] sulfonic acid derivatives of benzophenones, preferably2-hydroxy-4-methoxybenzophenone-5-sulfonic acid and salts thereof;

[0082] sulfonic acid derivatives of 3-benzylidene camphor such as, forexample, 4-(2-oxo-3-bornylidenemethyl)benzene sulfonic acid and2-methyl-5-(2-oxo-3-bomylidene)-sulfonic acid and salts thereof.

[0083] Typical UV-A filters are, in particular, derivatives of benzoylmethane such as, for example,1-(4′-tert.butylphenyl)-3-(4′-methoxyphenyl)-propane-1,3-dione,4-tert.butyl-4′-methoxydibenzoyl methane (Parsol 1789) or1-phenyl-3-(4′-isopropylphenyl)-propane-1,3-dione. The UV-A and UV-Bfilters may of course also be used in the form of mixtures. Besides thesoluble substances mentioned, insoluble light-blocking pigments, i.e.finely dispersed metal oxides or salts, may also be used for thispurpose. Examples of suitable metal oxides are, in particular, zincoxide and titanium dioxide and also oxides of iron, zirconium oxide,silicon, manganese, aluminum and cerium and mixtures thereof. Silicates(talcum), barium sulfate and zinc stearate may be used as salts. Theoxides and salts are used in the form of the pigments for skin-care andskin-protecting emulsions and decorative cosmetics. The particles shouldhave a mean diameter of less than 100 nm, preferably between 5 and 50 nmand more preferably between 15 and 30 nm. They may be spherical in shapealthough ellipsoidal particles or other non-spherical particles may alsobe used. The pigments may also be surface-treated, i.e. hydrophilized orhydrophobicized. Typical examples are coated titanium dioxides, forexample Titandioxid T 805 (Degussa) and Eusolex® T2000 (Merck). Suitablehydrophobic coating materials are, above all, silicones and, amongthese, especially trialkoxyoctylsilanes or simethicones. So-calledmicro- or nanopigments, for example micronized zinc oxide, arepreferably used in sun protection products.

[0084] Besides the two groups of primary sun protection factorsmentioned above, secondary sun protection factors of the antioxidanttype may also be used. Secondary sun protection factors of theantioxidant type interrupt the photochemical reaction chain which isinitiated when UV rays penetrate into the skin. Typical examples areamino acids (for example glycine, histidine, tyrosine, tryptophane) andderivatives thereof, imidazoles (for example urocanic acid) andderivatives thereof, peptides, such as D,L-carnosine, D-carnosine,L-carnosine and derivatives thereof (for example anserine), carotinoids,carotenes (for example α-carotene, β-carotene, lycopene) and derivativesthereof, chlorogenic acid and derivatives thereof, liponic acid andderivatives thereof (for example dihydroliponic acid), aurothioglucose,propylthiouracil and other thiols (for example thioredoxine,glutathione, cysteine, cystine, cystamine and glycosyl, N-acetyl,methyl, ethyl, propyl, amyl, butyl and lauryl, palmitoyl, oleyl,γ-linoleyl, cholesteryl and glyceryl esters thereof) and their salts,dilaurylthiodipropionate, distearylthiodipropionate, thiodipropionicacid and derivatives thereof (esters, ethers, peptides, lipids,nucleotides, nucleosides and salts) and sulfoximine compounds (forexample butionine sulfoximines, homocysteine sulfoximine, butioninesulfones, penta-, hexa- and heptathionine sulfoximine) in very smallcompatible dosages (for example pmole to μmole/kg), also (metal)chelators (for example α-hydroxyfatty acids, palmitic acid, phytic acid,lactoferrine), α-hydroxy acids (for example citric acid, lactic acid,malic acid), humic acid, bile acid, bile extracts, bilirubin,biliverdin, EDTA, EGTA and derivatives thereof, unsaturated fatty acidsand derivatives thereof (for example y-linolenic acid, linoleic acid,oleic acid), folic acid and derivatives thereof, ubiquinone andubiquinol and derivatives thereof, vitamin C and derivatives thereof(for example ascorbyl palmitate, Mg ascorbyl phosphate, ascorbylacetate), tocopherols and derivatives (for example vitamin E acetate),vitamin A and derivatives (vitamin A palmitate) and coniferyl benzoateof benzoin resin, rutinic acid and derivatives thereof, α-glycosylrutin, ferulic acid, furfurylidene glucitol, camosine, butylhydroxytoluene, butyl hydroxyanisole, nordihydroguaiac resin acid,nordihydroguaiaretic acid, trihydroxybutyrophenone, uric acid andderivatives thereof, mannose and derivatives thereof, superoxidedismutase, zinc and derivatives thereof (for example ZnO, ZnSO₄),selenium and derivatives thereof (for example selenium methionine),stilbenes and derivatives thereof (for example stilbene oxide,trans-stilbene oxide) and derivatives of these active substancessuitable for the purposes of the invention (salts, esters, ethers,sugars, nucleotides, nucleosides, peptides and lipids).
